“…According to Wening et al (2019), Fadhli et al (2020), and Anshori et al (2021), the yield test can be conducted effectively through a combination of primary and secondary characters in the form of a selection index, which is a method of selecting characters based on their weight (Simeao et al 2015). Subsequently, the combination is substituted into a multiple regression formula.…”

Abstract. Fadli M, Farid M, Yassi A, Nasaruddin, Anshori MF, Nur A, Suratman. 2021. Evaluation of the advanced yield trial on tropical wheat (Triticum aestivum) mutant lines using selection index and multivariate analysis. Biodiversitas 23: 540-547. The development of adaptive wheat (Triticum aestivum L.) mutant lines in tropical climate is a long-term solution. The advanced yield trial is an important stage in this development, which is carried out using a selection index and multivariate analysis. This study aims to determine the selection effectiveness of tropical wheat mutant lines by using a selection index and multivariate analysis. the study was conducted in three locations, which included two locations for the follow-up yield test in Kelara Village and Ujung Bulu Village (South Sulawesi, Indonesia), and the third location for the selection validation in Padang Magek Village (West Sumatra, Indonesia). This study was designed by a nested Randomized Complete Block Design (RCBD), with replications nested in locations. The samples included 16 wheat genotypes (13 mutant lines and three comparison varieties) that were replicated three times. The result showed that the selection of tropical wheat mutant lines using selection index and multivariate analysis were considered effectively with high determination value of 0.57 (57%). The results of the selection index show that seven lines were recommended for multi-location trials since they had a better selection index potential than Dewata variety.

“…Rao et al [16] reported significant difference for majority of the trait reported here except flowering time and maturity. Wening et al [17] reported significant effect of genotype and G x E for days to flowering among 17 rice genotypes evaluated under optimum and submerged conditions. Table 2 presents the mean performance and coefficients of variation for flag leaf width (FLW), flag leaf length (FLL) and straw girth (SG) among the six generations of the crosses (Cross I and Cross II) evaluated under normal and submerged conditions.…”

“…The effect of submergence on phenotypic variation of rice plants has been widely assessed by several researchers [20,21]. Possible selection criteria for submergence superior rice genotypes were documented by Wening et al [17]. Rao et al [16] reported that high phenotypic variation among six generations of a rice cross evaluated under submerged condition.…”

Submergence tolerance has long been regarded as an important breeding objective for rain-fed lowland and deep water rice area. Despite this recognition, there has been limited success in developing rice with improved submergence tolerance in Africa. The present research was aimed at assessing performance of crosses under submergence stressed and non-stressed conditions in Nigeria. Six generations of the crosses were evaluated under optimum and submerged conditions in a complete randomized block design with three replications. Submergence screening was performed in controlled conditions that allowed flooding at a water depth of 1.0 meter for a period of 14 days. The results revealed that significant difference among the generations of the two crosses evaluated. The observed survival rate (%) in Cross I of the generations ranged between 0.00% - 100% while in Cross II, it ranged between 0.00% and 95.24%. The Phenotypic Coefficients of Variation (PCV) and the Genotypic Coefficient of Variation (GCV) for 100 grain weight were moderate to high under the two conditions. Low to moderate PCV and GCV coefficients of variation were observed for the grain width and grain length under both conditions in the two crosses. High heritability (0.96% respectively) and high genetic advance as percentage of mean were recorded for the grain yield and grain weight in the two crosses. The variability observed among the generations was optimum however, advancement of the segregating generations coupled with adequate selection criteria could lead to identification of superior and stable genotypes for farmers’ use.

“…The grouping was understandable because MR14 and NEI9008 are line seeds and the others were hybrid maize. The heatmaps method helps the researcher classify genotypes based on their characteristics, i.e., tolerant and sensitive genotypes[19,20].…”

Determination of check genotypes for maize biomass and grain production on the tidal swamp acid soil environment was randomly picked among the genotypes, regarding of the lack information about check genotypes characteristics on tidal swampland. This study aimed to analyze maize check genotype characteristics on a tidal swamp. Five check genotypes (open-pollinated variety=Sukmaraga, hybrid variety=P27, elite lines=NEI9008, elite lines=MR14, three-way cross hybrid=Bima20URI) was planted among 150 maize lines, tested on tidal swampland in three environment treatment (saturated soil culture/SSC, saturated soil culture+temporary flooding/SSC+TF, and acid dry land/DL). Augmented Randomized Complete Block Design (Augmented RCBD) with five replications was used for this experiment. Data were analyzed using PBSTAT-CL 2.1 statistic tool. The result showed that SSC was the most suitable land management technique for maize plant crops in tidal swamp acid soil. Bima20URI grain biomass production was high in SSC land management of tidal swamp environment. Meanwhile, P27 hybrid variety was ideal for all treatments and adaptable to stressed environment. Sukmaraga was unstable genotype on the and declined on SSC+TF but suitable for SSC. NEI9008 genotypes have high productivity in stressed environments, and MR14 line genotype has stable grain production in every treatment environment yet has lower grain productivity.
